What is OpenCore?

OpenCore is a sophisticated boot loader used to inject and patch data in memory, instead of on disk. This means that we're able to achieve a near-native experience on many unsupported Macs.

We recommend viewing the OpenCore Patcher Terminology Page if you have questions.

For troubleshooting, see our troubleshooting pages below or join the OpenCore Patcher Paradise Discord Server. (opens new window)
